CVE-2018-18573
Remote authenticated administrators can upload new '.htaccess' files (e.g., omitting .php) and subsequently achieve arbitrary PHP code execution via a /catalog/admin/categories.php?cPath=&action=new_product URI.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
